WebDec 11, 2024 · TTT (Time-temperature transformation) diagram is also called an Isothermal transformation diagram. Above eutectoid temperature: only austenite exists. Below eutectoid temperature: nucleation + growth. The percentage of the transformation product is related to the holding temperature and holding time. Isothermal transformation diagrams (also known as time-temperature-transformation (TTT) diagrams) are plots of temperature versus time (usually on a logarithmic scale). They are generated from percentage transformation-vs time measurements, and are useful for understanding the transformations of an alloy steel at elevated temperatures.
